SEAL-LOCK.

SPECIFICATION forming part of Letters Patent No. 648,564, dated May 1,1900.

Application filed October 30, 1899. Serial No. 735,146. (No model.)

To @ZZ whom it may concern.'

Beit known that I, LOUIS A. HOERR, a citizen of the United States ofAmerica, residing at St. Louis, inthe State of Missouri, have invented acertain new and useful Seal-Lock, of

which the following is such a full,clear,and exact description as willenable any one skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, forming partof this specification. l

My seal-lock is especially adapted for use in connection with a iiushdoor which is moved laterally by means of a rock-shaft; but it may beused in connection with various other kinds of doors.

My invention consists in'various novel features and details ofconstruction,'all of which are shown in the following specification andpointed out in the claims affixed hereto.

In the accompanying drawings, which illustrate a seal-lock made inaccordance with my invention, Figure 1 is a front elevation. Fig. 2 is atop plan view. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4isan end elevation, and Fig. 5 is a section on the line 5 5 'of Fig. 1.

Like marks of reference refer to similar parts in the several views ofthe drawings.

represents a rock-shaft which may operate to move the door in and outlaterally by any suitable mechanism. The end of the rock-shaft 10 isjournaled in -a lug 1l, secured to -the door by bolts 12 o r Vin anyother suitable way. Secured to the rock-shaft 10, preferably by means ofa rivet13, is a hasp 14. The end 15 of the hasp 14 is made thin, as bestshown in Fig. 3, and is preferably provided with an outturned part 16and seal-wire opening 17 20is the keeper, which is secured tothe cardoorby means of bolts 21, passing through openings 22, Fig. 5. The keeper 2Ois provided witha forwardly-projecting part 23,thusleavingarearpocket24. Theforwardlyprojecting part 23 is arranged soas to come above the hasp 14 when it is in its closed position. Formedin the forwardly-projecting part 23 is a slot 25, which communicateswith the rear pocket 24. Projecting through the slot 25 is a pin 26,provided with a cylindrical head 27 The ends of the head 27 projectat lthe sides of the pin 26 and form trunnions which slide in the rearpocket 24. The upper end 28 of the pin 26 is made square, as best shownin Fig. 5, so that the pin 26 cannot be removed from the keeper byturning it in a horizontal position and withdrawing the head 27 throughthe slot 25. The keeper 2O is provided below the hasp 14 with aforwardlyprojecting loop 29, which is adapted to receive the end of thepin 26. Formed in the lower end of the pin 26 is a seal-wire opening 30.

In using my seal-lock the pin 26 is slid upwardly until the head 27strikes the upper end of the pocket 24. The pin can then be swungoutwardly and upwardly, the ends of the head 27 acting as trunnions, soas to leave the hasp 14 free to be drawn outwardly to rotate therock-shaft 10. In closing the door the above movements are reversed andthe lock is sealed either by passing a seal-wire through the seal-wireopening 30 or through both the vseal-wire openings 30 and 17.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is

l. In a seal-lock, the combination with a keeper provided with arearwardly and'laterally opening elongated pocket and aforwardly-opening slot, of a pin .provided with an integral cylindricalhead, the endsof which project at the sides of said pin and formtrunnions, said trunnions sliding in said pocket, and a loop carried bysaid keeper and coperating with said pin.

2. In a seal-lock, the combination with the keeper 2O provided with therearwardly and laterally opening pocket 23 and forwardlyopening slot 25,of the pin 26 provided with the cylindrical head 27 and square end 2Sfor preventing the turning of said pin and withdrawal of said headthrough said slot 25, and the loop 29 carried by said keeper andcoperating with said pin.

In testimony whereof I have hereunto set my hand and affixed my seal inthe presence of the two subscribing witnesses.

LOUIS A. HOERR.
